Did the infamous Dr. Xavier Rath give Twisted Fate his magic power? Or was it Dr. Aregor Priggs, a high-ranking Zaunite official and businessman?
According to TF's lore, his insane thirst for magic led him to volunteer for a magic experiment AFTER he learned about it being conducted in Zaun.
In Graves's lore, TF was offered by a different person magic power in a deal to serve Graves up.

Are these two doctors business partners? Or are they the same person?
Also, was TF offered this deal or did her learn about it?

Priggs is the one that introduced TF to the doctor Ranth that was making the experiment.
